aluminium pcb

    LED aluminium pcb is a special material PCB, which is the meaning of printed circuit board. This PCB material is aluminium alloy, but the general circuit board material is glass fiber. Because the LED heat is larger, the PCB for LED lamps and lanterns is commonly aluminium pcb, which can fast heat conduction. So aluminium pcb usually are used in LED lighting products. Aluminium pcb has two sides. One side of aluminium pcb is used to weld the LED pin; the other side of aluminium pcb is Aluminum color, and it usually are applied with thermal condensation. Expecting aluminium pcb, there are other types of PCB, such as ceramic pcb, and so on.

   Aluminium pcb is a kind of metal base copper clad laminate with a good cooling function. and common aluminium pcb is composed of three layers: respectively the circuit layer (copper foil), insulation and metal base. For high-end use, there is also a  double-sided board design: circuit layer, insulating layer, aluminum structure, insulation layer and circuit layer. Few aluminium pcb are designed as sandwich plates, which is composed by ordinary sandwich plate and insulation layer and aluminum joint.

Working principle of aluminium pcb:

Power device in surface-mount circuit layer, the heat generated by the device at runtime by rapid transmission to the base metal, insulation layer and the metal transfer heat out at the grassroots level to achieve cooling on the device.

Advantage of aluminium pcb:
1.Compared with traditional FR - 4, aluminium material can minimizes thermal resistance, which make the aluminium pcb has an excellent heat transfer performance.
2.Compared with thick film ceramic circuit, aluminium pcb has a better mechanical performance.
3.Aluminium pcb conforms to the requirements of the RoHs.
4.Aluminium pcb is more adapted to the SMT processing.

5.Instead of brittle ceramic substrates, Aluminium pcb has a better mechanical endurance.
